Spatio-Temporal Simulation of Ultrashort Phenomena in Different Optical Systems

San Francisco, 2 February 2020, SPIE Photonics West

We will present our modeling concept including both temporal and spatial properties of ultrashort pulses based on physical optics. The modeling of the pulses starts with a temporal Fourier transform which convert the temporal signal into correlated spectral modes, so that the material dispersion effects can be included. Each spectral mode is polarized and therefore vectorial electromagnetic field information can be considered. Based on the concept of field tracing, we investigate the interaction of ultrashort pulses with different types of optical components, including lenses, mirrors, as well as diffractive gratings and even metasurfaces.
